PATENT OFFICE DE'ABBOBN, MICHIGAN, A oonrona rion ornELAwAnn a Origi'nal application filed August 15,

i The object of my invention to provide a-doorlatch of simple, durable and inexpensive construction; p a y y Still a further object of my invention is to providea door latoh specially adapted for use in connection with the doors of an automotive vehicle wherebythe door pillars may be of -a minimum thickness to thereby make the vision from the body greater and whereby the controls for; opening the latch may be very conveniently placed. a

Still a further object of invention is to provide a door latch for. an automobile handle may be disposed at'a place spaced very materially-from the door pillarand thedoor latch may be shaped to pass around the edge u of the door glass to thereby make the latch construction compact and so that it will. not materially increase thercross sectional area of the door pillar. f

Still a further obj ectof my invention is to provide a door latch for usein connection with a sheet metal door wherein the latch is formed from a strip of'sheet metal which is bent angularly at various points along its lengthto provide a bridge extending around the edge of the door glassand-a lug at either end which IIlEtYibGOPBI'Eltt-ZCI by the adjacent operated from either the inside or the outside of the door,'and still it is not necessary to run any. parts of the lock directly through thedoor pillar to thereby increase the necessary cross sectional area of said pillar.

Still a further object of my invention is to provide means which will not materially increase the cross sectional area of thedoor pillar and which may extend across thelouter With these and other objects in vietvmy invention consists in the. arrangement, C0l11- bination, and construction of the various parts of my improved device as describedin the specifications,claimedin the claims and illustrated inthe accompanying drawings in which: i Figure 1 shows an elevation rmy improved door. latch looking alongthe inside of the door toward the .doorpilltti the glass channel and glass being removed in'order to better illustrate the construction.

Figure 2 shows a horizontal sectional view through the door and body pillar-taken on the line 2-2 of Figure 1,.the inside operat ing handle .being shown to better illustrate the construction.

Referring to the accompanying drawings I have used the reference numeral 10 to indicate the outside door panel and reference numeral 11 to indicate the inside door panel. These partsare connected at the free edge of the door by the door pillar 12. This door pillar 12 is recessed near the central part thereof to receive a latch plate 13 which is suitably securedto the pillar 12 by rivets 14. This latch plate is provided with a recess within the central upper portion there- 1927, Serial No, 212,909.

It will be noted ithatthisrodeii- 'may be of any suitable length so'thatthefhandle46 1 may beplacedatthemostconvenientgplace for the operator of the car-to reach. A

spring 47' is ,.designed to: coact. with the rod 453- to return to'the normal'positionwith the arm 45 stopped against'a stop 72 formed in tegral with the clip'42' and to prevent r'attle thereof. a

' ordinary automobile body and that the door latches are provided with an auxiliary looking means which may be operated from the inside in connection withthe locks for theremaining doors so that they may not be opened by unauthorized persons from the outside.

Such a means is provided with my improved'door latch and comprises a pair of clips 48 which are riveted to the inner door panel 11 to provide a sliding bearing for a bolt 49. This bolt 49 is provided with an operating handle 50 which is secured to the bolt 49 and extends through appropriate slots 51 in the clips 48 and the door panel 11 to permit the handle 50 to be reciprocated to reciprocate bolt 49. A second bolt 52 is mounted on the latch plate 13 for reciprocation in a groove 53 in the plate 13. This bolt 52 is bent upon itself intermediate of,

its ends to form a stop member 68 designed when the bolt is in its extended position to form a stop for a downwardly extending lug on the dog 21. It will thus be seen that when bolt 52 is in itsextended position the stop portion 68 of said bolt will extend between the lug 55 and the latch plate 13 to prevent rotation of the rollback 21. Hence the outside door handle cannot be used to retract the latch 15 when the bolt 52 is in its extended position. A retaining clip 54 is suitably secured to the inside of plate 13 to slidably secure bolt 52 in the groove 53. Movement of the bolt 49 parallel with the surface of door panel 11 is transmitted into movement of the bolt 52 along the face of the latch plate 13 by means of the inclined handle 50. The spring 69 prevents rattle of ends of said bolts as is illustrated at 56 in Figure 4.

A coil spring 69 has one end engaged in a slot in a stud 70,ywhich extends from the r latch plate 13, and the other end bearing against the stop member68 of the bolt 52, to thereby normally urge the bolt 52 to retracted position. An offset 71 is provided in the bolt 52 to co-act with the inclined end of bolt 49 to resist the action of the spring 69 when the bolts 49 and 52 are in extended or operative position. Movement of the stop 68 is entirely manually controlled from the the parts in their retracted position and resiliently holds the bolt 49 in its forward or engaged posit-ion thru the offset 71.

Referring to Figure 4 it will also be noted that glass channel 57 which is normally disposed adjacent to'a door pillar 12 contains a felt channel 58 in which a glass 59 may slide. Referring to Figure 2 it will be noted that this channel 57 extends to position contiguous to the door pillar 12.

Door latch 15 coacts with an adjustable striker plate 62 which is moved to the desired position within a 'channel63 which forms a part of the body pillar 64. Adjustment of the striker plate 62 is accomplished by looseningscrew to thereby permit thestriker plate 62 toslide along thechannel 63 to p0 sition to latch the door so that it will not rattle. Tightening screw 65 will thenlock the striker plate due to the serrations onthe bottom ofthe plate andthechannel Among the many advantagesari sing from my improved latch it will be seenthat I have provided means whereby the glass channel may rest-against the central portion of the a door pillar so that the total blind spot? be as small as possible. a i

Still a further advantage results frointhe use of my improved device in that separate spring means are provided for returning practically all ofthe parts to normal position so that rattle is largely eliminated. Still a further advantage results from providing means for mounting the inside door handle whereby it may be extended to the position'niost convenient for the operator, and whereby the extended inside door handle may be mounted on the door with few additional parts and little change in the panel.

. Still a further advantage results from the may use of my improved latchdevice for the prevention ofopening doors from the outside, as

this does not materially add to the thickness of thedoor pillar.
